On a stormy night, the seemingly lifeless beautiful Marina is born. The baby is welcomed by Damiana, the village midwife, who a few hours earlier delivered a healthy child, but unfortunately his mother did not survive. Don Luis, Marina's father, since he married Prudencia, has been determined to have a son, for which reason he constantly warns his wife that, otherwise, he will leave her for another that he can give her. an heir that transcends his illustrious Ocaranza surname. Unfortunately, Prudencia is unable to get pregnant again, a situation that urges her nanny Angustias to convince Damiana to benefit the family and the baby who was orphaned and pass him off as Ocaranza Arzuaga's legitimate son. This is how Alberto, the great pride of Don Luis, grew up in a cradle of gold and traveled abroad to study medicine.
